    General description

    Potassium thiocyanate is an inorganic potassium salt. Phase transitions in potassium thiocyanate (KSCN) have been investigated by X-ray diffraction studies. The order-disorder type transition with respect to the orientation of the thiocyanate ions was identified.[1] Its polarized infrared spectrum has been reported.[2] It participates in the ring-opening of aziridines. The reaction was carried out in the presence of sulfated zirconia to afford the corresponding β-aminothiocyanates.[3]

    Application

    Potassium thiocyanate (KSCN) may be used for the colorimetric quantification of intracellular iron content of the superparamagnetic iron oxide (SPIO) nanoparticles.[4]
    Potassium thiocyanate may be used in the synthesis of the following:
    • α-Amino nitriles from tertiary amines.[5]
    • Polysubstituted 2-aminothiazoles from vinyl azides.[6]
    • Benzisothiazol-3(2H)-one derivatives from o-bromobenzamides.[7]
    • Diaryl thioethers from aryl halides.[8]
